A video of a man using sound to create geometric shapes out of couscous has gone viral on Twitter—and it’s easy to see why.

The original video was published on YouTube in 2016 by Steve Mould, “a science presenter on TV and on stage,” who participates in the science-comedy show Festival Of The Spoken Nerd.

In the video, which has received over 1 million views, Mould uses a large sheet of metal, a violin bow and couscous (uncooked, as he points out) to demonstrate two-dimensional standing waves in the form of “Chladni figures.”

As Mould explains, the amazing geometric shapes are named after Ernst Chladni, the German physicist who invented this technique to display them around 1787—although he used sand instead of couscous.

Mould then goes on to explain how the actual math that explains the phenomenon was largely discovered by mathematician Sophie Germain, who received very little recognition for her work during her lifetime.

Prepare to be dazzled:

On Tuesday, an edited version of the video was posted on Twitter, by experimental social psychologist Simone Schnall, where it has since racked up over 2 million views, 57,000 retweets and 160,000 likes.

There’s a documentary about Roslin chapel here in Scotland, the architect who designed it carved resonance symbols at the top of each pillar in the chapel. When each symbol is played in order it made a song that had been forgotten by time, immortalised in the form of symbols.

This is also similar patterns that you can see when you close your eyes while on LSD and listening to music. Different songs create different patterns visually, they move, alternate, and change shapes. Almost like a story behind every song.
